Based on the characters in DC Comics’ John Constantine stories, the project centers on John Constantine (Ryan), an enigmatic and irreverent con man-turned-reluctant supernatural detective who is thrust into the role of Constantine defending us against dark forces from beyond.

John Constantine is described as a working-class Londoner with rakish good looks, scruffy blond hair, deadpan humor, and signature trench coat, who has been studying the dark arts since he was a teenager. When the daughter of a late friend is targeted by demons, Constantine steps in to save her.

The project was written by The Mentalist executive producer Daniel Cerone from a story he co-penned with David S. Goyer, the go-to writer for Warner Bros’ feature DC adaptations who has co-penned The Dark Knight, The Dark Knight Rises, Batman Begins, Man Of Steel and the upcoming Batman vs. Superman.
